Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55812, here are decompositions:

5 + 55807 = 55812
13 + 55799 = 55812
19 + 55793 = 55812
79 + 55733 = 55812
101 + 55711 = 55812
131 + 55681 = 55812
139 + 55673 = 55812
149 + 55663 = 55812

Showing the first eight; more decompositions exist.
